THE CONGRUENT NUMBER PROBLEM 1. Introduction A right
... Whether or not n is congruent is related to solvability of pairs of equations: first, by definition we need to solve a2 + b2 = c2 and (1/2)ab = n in positive rational numbers a, b, and c. In Section 3 we saw this is equivalent to solving a second pair of equations in positive rational numbers: s2 − ...

Elements of R{Y } can be understood as differential operators on R, in light of the natural ring homomorphism R{Y } → End(R) sending Y (i) to ...
